MODÉLISATION 3D & ANALYSE DU COMPORTEMENT MODAL D’UNE PALE D’ÉOLIENNE À AXE VERTICAL DE TYPE DARRIEUS

Abstract

ii ABSTRACT The work presented in this thesis focuses on the exploitation of Computer-Aided Design CAD/CAM, within the Finite Element Method analysis context for the modal analysis of low-power vertical axis wind turbine straight blade based on the 3D mechanical industrial software SolidWorks Simulation. This study is part of a research project aimed Mechanical design and advanced vibratory of direct-attack 10 kW H-Darrieus vertical-axis wind turbines on site Adrar. Modal analysis of blade is made for the prediction of optimal structural parameters in terms of frequencies, eigen modes, Effective Mass Participation (EMP). The purpose of the analysis is to set the resonance conditions of the structure under the external wind disturbances which ensure the stability, safety and dynamic reliability of the structure.
